Simple curve track frames are already known, which can be used as right and left switches by turning in their plane. These curve track frames do not allow of the straight track being travelled over. The curve track frame must be removed from the track if straight track is to he travelled over.

Inclined plane switches are also known, which can be used as right or left switches and at the same time allow the straight track to be used. In these inclined plane switches the track rails for one direction of travel are also the grooves for the other travelling direction. These switches have long straight track rails for travelling over the straight track and are therefore so heavy that they can only be turned by two men. Besides which they have a crossing which is very complicated to forge.

By theimprovement hereinafter described an inclined plane. switch is produced which can serve as right and left switch and at the same time allows the use of the straight track. The new inclined plane switch is so light that it can easily be turned by one man. Only its Fig. 1 the switch being however arranged as left switch.

Fig. 3 is a top planview of the inclined plane switch.

The remaining Figures 4 to 18 show constructional details of the switch.

1 and 2 are the bent track rails. 3, 1, 5, 6 are facing and tailing tongues extending tangentially to the bent track rails 1 and 2. 7

and 8 are grooves arranged in the bent track rails 1 at the commencement of the running on and running off tongues 3 and 5 respec tively in order to leave a free passage for the wheel flanges of the cars, after the car wheels have run off the tongues 3, a or 5, 6 respectively and have again reached the rail level.

In order to determine the travelling direction two ton'g'ties 17 and 18" are i'is'e'd, which are swivelled on thebolts lt) and 20; The tongue 18' is shown in dotted lines in Fig. 8 ins position giving free "passage for the straight line of rails 1 -1; The tongue 17. is only actiiattl when the switch is used as free'th'e through-line a mile 11 11. on the othe'i- 'haiid, when the switch used asleft switch,- the tongue 17 re'l'nai-ns in tile position shown in dotted lines in 3 witlithroughline of rails I 'I ffed for assage. i i In order to be able to iil'alie the tongues cheaply, that is (if 's'heet met-Junie tongues have been giventhe' new Z-like shape shown inFig. 1. The t on ufe's' '17 and 18 respec may serve only as g hidin'g elements, whereas the parts 52L, antiwar the track 5 and 1, situated thereunder; take uptlie whri'zl stresses. A nose 21 arranged the side of the Z-prbfile engages ovrthe track rail listed under are wages are severe sllof tongiie; For coh'nectin the two curved lines of rail 1 and 2 ties 22 and 23 are arranged, one at each end of the switch. Figs. 5 to 13 show sections corresponding to the section lines indicated by letters in Figs. 3 and 4. For the grooves 7, 8 and the joining flat surfaces 9, 10 the crossing shown in Figs. 14 to 18 may be substiuted. This arrange- UH ment presents the advantage, that the car wheel, after leaving the'tongue 17 or 18 respectively, has not to run over any fiat sur-i faces and grooves W1th its flange, its flange runmng on onto thetrack rail 5b leading up to the crossing to be taken over by the point 24 of the crossing without shock, which point .allows the wheel to run 011? onto the rail head like the running-on tongue of the track rail 7 2. In travelling over the straight line of rails II on-ewheel of the car axle continues to run on the rail, whereas the other wheel is raised by the running-on tongue 25 extend ing through the crossing 24 and is again lowered onto the head of the railby its downwardly inclined'surface 24a (Fig. 16).

1. 'An inclined, planecurved switch, comprising incombination a bent curved frame composed of curved track rails one of said track rails having grooves, tangential extending running-on, and running-off tongues connected to said frame at the point where said grooves begin, and upwardly pro ecting guide bridges mounted on the track rail without grooves.

2. An inclined plane curved switch, comprising in combination with .a bent curved it'rame composed of track rails connected by a tie at each end and tangentially extending running-0n and running-oil tongues connected to said rail the tongues made of sheet metal" pressed to Z-shaped cross-section adapted; to guide the wheels, the supporting of the Wheels being elfected by the track rails situated under said tongues.

4. An inclined plane curved switch, comprising in combination with abent curved frame composed of straight and bent lines of rails, crossings arranged; between said stralght and bent llnes of ralls said crossings having running-on and running-off surfaces allowlng the stralght line of rails to be travelled over, one of the wheels continu ng to 7 run on the track rail the other wheel travelling over said crossing owing to the gently in;

clined running on and-running off surfaces.

In testimony whereof I aflix my signature.
